Re: [PATCH v1] Re: [mkgmap-dev] maxspeed tag vs road_speed preset
Hi Mark, It occurs to me that some people will want the maxspeed tag to override the speed code in the rules file (obviously, the person who wrote that code thought it was a good idea) but others, like Marco, would prefer not to have that feature. So, I guess, we need (yet another) option to control this behaviour. I attach a patch that does, essentially, the same thing as your patch with the addition that you can switch that behaviour on and off. Thank you for that patch. The patch I posted was intended to be applied locally if one wanted to remove that behaviour. With the state of mkgmap right now I think it is reasonable to hardcode such things as the maxspeed, because otherwise the style files will get overly complex and with the current syntax of the style files a lot of things can not be encoded at all (for example motorway exits, roundabouts etc.) For special map- tuning one will have to modify the mkgmap source. Which is probably even easier than coming up with highly complex style files to accomplish the same thing. So if you like to integrate the switch for the maxspeed handling into the trunk I will be happy, but I also understand that you might not want mkgmap to be cluttered with lots of special options.

[PATCH v1] Re: [mkgmap-dev] maxspeed tag vs road_speed preset
Hi, and thaks for your answer. I'm not a developer so I really have some problem in applying the patch locally... I just would like to keep control over the map generation. For example: in Italy the maxspeed out of the city is 90km/h. It applies to unclassified roads up to trunk roads (well, some trunks has 110 km/h). I would like to code in the map in a way that a tertiary with 90km/h speed limit gets road_speed 3 (i.e 60 km effective speed), while a trunk with the same 90km/h limit gets road_speed 5 (i.e 90 km/h effective speed). You can immagine for the secondary and primary. I looked at the source and you coded: if maxspeed40 then road_speed=3 It means that in the Italian cities (limit=50) the average speed coded in the map is 60km/h. It looks strange to me and carries to very optimistic city ETA calculations (and maybe not optimal route selection). Moreover, I sow other map makers (DE:All_in_one_Garmin_Map) making maps including the maxspeed tag management in their styles (but maybe they use a patched mkgmap). So, if it counts I do vote for the switch --ignore-maxspeed and I vote to integrate the patch in the mainstream mkgmap (again, I'm not able to compile the code).

Hi Thilo, So if you like to integrate the switch for the maxspeed handling into the trunk I will be happy, but I also understand that you might not want mkgmap to be cluttered with lots of special options. Well, I don't have a problem with lots of options so I am happy to commit that patch if people are agreed that it's useful.
